Endovascular repair of a right-sided thoracic aortic aneurysm with Kommerell diverticulum and aberrant left subclavian artery.

BACKGROUND

A case of successful total endovascular repair of a right-sided descending thoracic aorta aneurysm (r-DTAA) with Kommerell diverticulum and aberrant left subclavian artery (ALSA) was reported. Few cases of this very rare pathology were reported, mostly describing a hybrid treatment, with only 2 cases of total endovascular repair performed to date.

METHODS AND

RESULTS

Our strategy consisted of endovascular ALSA occlusion, without preventive revascularization, and r-DTAA exclusion by 2 endoprosthesis implanted in a telescopic fashion, first the distal one, to achieve a relative straightening of the arch and support the proximal endoprosthesis, and then the proximal one, close to the right subclavian origin. Completion angiography and 12-month computed tomography scan showed successful exclusion, patency of epiaortic vessels, and absence of endoleak.

CONCLUSION

Endovascular repair can be a safe and effective treatment for aortic disease with challenging anatomy, avoiding the need for a complex open surgery procedure.
